Device for mounting a rail or the like on a surface

Abstract

A device for mounting a rail (1) on a surface which particularly is non-horizontal, comprises at least one mounting element (11) adapted to be secured on said surface, at least one connecting element, which is displaceably received in a guide extending along the rail and an engaging arrangement having means for mutual clamping connection of the connecting element and the mounting element in order to connect the rail with the mounting element. The engaging arrangement comprises means (23, 24) for provisionally coupling the connecting element and the mounting element by means of a hooking movement of the connecting element having a movement component substantially parallel to said surface.
